X-NUCLEO-IKS01A3 driver for Arduino [Copy link]

 

 

Well, I participated in an event and was given a board for free, but the prerequisite was to debug and port it to an MCU, so I wrote the Arduino UNO. Then after I got it, I found that ST actually wrote the STM32duino library here
[https://github.com/stm32duino/X-NUCLEO-IKS01A3](https://github.com/stm32duino/X-NUCLEO-IKS01A3)
and the technical manual is here
[https://www.st.com/content/ccc/resource/technical/document/user_manual/group1/22/ae/90/6d/9f/03/4e/45/DM006 01501/files/DM00601501.pdf/jcr:content/translations/en.DM00601501.pdf](https://www.st.com/content/ccc/resource/technical/document/user_manual/group1/22/ae/90/6d/9f/03/4e/45/DM00601501/files/DM00601501 .pdf/jcr:content/translations/en.DM00601501.pdf)

But there is a problem that this library cannot be used directly after getting it. . .
I will write down how to use this library. .
First, download this library and put it under the Arduino library. When you open the example, you will find that various files cannot be found. Then you need to put back the libraries listed on GitHub.

Then open hello world, the first problem is that float_t is undefined

Open the file and add this definition.

Then there are two errors
[attach] 423579 [/attach]
The first one is that the description file of HTS221 says that it does not support avr, but only supports stm32. I tried it and it can run directly. If you want to solve it, open this here [attach] 423580 [/attach]

Add avr

to the last line

Another way is to compare uint and int, just add a type conversion in front of it

This will compile fine.

However, when I tested it, there was no output at first. Later, I wrote an i2c_scanner and scanned it, and it worked again. I’m not sure why... I found that a code I wrote had a similar problem because I didn’t write i2c.begin(); it worked fine after adding it, but when I looked back at the sample code, it seemed to be there. I don’t know what’s going on...

Um... Does anyone know how to send attachments?

There is no output at first, it is likely that the contact of the Arduino interface is not good.

I'll try

Well, since the flashing is OK, I think this is not the problem.

Arduio has direct examples and CPP functions, which are very well written, but difficult to understand.

The advantage of Arduino is that it is easy to copy and use, the disadvantage is that it is difficult to improve and debug.

Yes, all packaged into C++;

Well, I personally think the encapsulation is OK. You can basically use it after looking at the example.

Enable it in setup, and get it when you want to use it

Um... Where can I edit an article that has already been posted? I want to add an attachment but I can't find it.

I really can't find where to upload the file... I uploaded the file to Baidu Cloud, the link is on the 11th floor...
